    Abstract: Provided are an electrolytic copper foil, an electrode and a lithium-ion cell comprising the same. The electrolytic copper foil has a first surface and a second surface opposite the first surface. An absolute difference of the FWHM of the characteristic peaks of (111) planes of the first surface and the second surface analyzed by GIXRD is less than 0.14, the first and the second surfaces each have a nanoindentation hardness of 0.3 GPa to 3.0 GPa, and the yield strength of the electrolytic copper foil is more than 230 MPa. By controlling the absolute difference of the FWHM of the characteristic peaks of (111) plane of these two surfaces, the nanoindentation hardness of these two surfaces and the yield strength, the electrolytic copper foil can have improved tolerance to the repeated charging and discharging and reduced warpage, thereby improving the yield rate and value of the lithium-ion cell.
